Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and in particular to an automated construction platform for a tunnel portal section lining structure. Background Art

[0002] During tunnel construction, the surrounding rock at the tunnel portal is highly susceptible to collapse. To prevent this from happening due to gravity, reinforced concrete is poured as the tunnel lining. Tunnel lining construction is a critical step in tunnel engineering, and its quality directly impacts the tunnel's safety, durability, and functionality. The lining construction platform, an integrated equipment platform integrating concrete pouring and vibrating, is an essential, non-standard product for tunnel secondary lining construction.

[0003] During lining construction, end formwork must be installed at the front and rear ends of the top and side formwork to limit the flow of concrete and ensure that the thickness, curvature, and clearance dimensions of the lining end are exactly as designed. Currently, during lining construction, end formwork is often pre-stacked on the lining platform and then manually moved by construction workers during installation. Because the tunnel side formwork covers a large area, additional climbing tools are required when moving it to a higher position, resulting in low installation efficiency for the end formwork.

[0016] Beneficial effects of the present invention:

[0017] (1) By setting up a transfer component, when the end template is clamped and fixed, the slide drives the cross plate to move linearly along the guide rail, and cooperates with the sliding sleeve to drive the cross plate to rotate along the annular slide rail, so that the cross plate gradually approaches the side steel templates on both sides, and uses the support slide to drive the mounting plate to move along the linear slide groove, which can effectively adjust the horizontal position of the end template, and uses the rotation process of the cross plate to drive the cross plate to adjust the pitch angle, which can effectively adjust the height position of the end template. At the same time, the leveling cylinder is used to adjust the inclination angle of the mounting plate, so that the mounting plate can always remain horizontal during the deflection of the cross plate, ensuring that the end template remains stable and does not tilt during the transfer process. When the end template is transferred to the designated workstation, the clamping plate can be released to unload the end template, thereby realizing the rapid transfer process of the end template from the construction platform to the installation workstation, which is conducive to improving the efficiency of lining construction and greatly reducing the labor intensity of workers.

[0018] (2) By setting the clamping plate, the movable plate utilizes the sliding fit between the pin rod and the matching groove during the linear displacement process, combined with the mirror arrangement of the matching groove and the equidistant distribution design of the end portion, so that the clamping plates can be equidistantly approached to each other for gathering, and equidistantly moved away from each other for dispersion, thereby being able to clamp or loosen multiple sets of end templates at the same time. Moreover, since the clamping spacing between adjacent clamping plates is always consistent, the thickness of the clamped end templates should also be consistent. After multiple sets of end templates are clamped and fixed, it is possible to intuitively judge whether their thickness meets the construction standard based on whether some of the templates are loose, thereby realizing the thickness detection and screening process of the end templates, which is beneficial to improving the quality of lining construction.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 3 As shown, the present invention is an automated construction platform for the lining structure of a tunnel portal section, comprising a frame 1, a construction platform 2 fixedly provided at the front and rear ends of the frame 1, a top steel formwork 3 provided at the top of the frame 1, side steel formwork 4 provided on the left and right sides of the frame 1, a power assembly 6 provided at both ends of the bottom of the frame 1, the power assembly 6 drives the frame 1 to move along a driving track 5, an operating platform window 21 provided on one side of the construction platform 2, an escalator 22 extending downward from the edge of the construction platform 2, and a transfer assembly 7 for transferring the end template provided at the bottom of the construction platform 2.

[0032] Specifically, during the construction process, after the top steel formwork 3 and the side steel formwork 4 are pushed into place, the staff can move the end formwork stacked in advance on the construction platform 2 to the transfer assembly 7 through the operating platform window 21, and the transfer assembly 7 deflects and lifts the end formwork to transfer the end formwork to the desired position, which greatly improves the construction efficiency and effectively reduces the labor intensity of the workers.

[0033] like Figure 2-Figure 8 As shown, the transfer assembly 7 includes a guide rail 71, which is fixedly mounted on the bottom of the construction platform 2, and a slide 72 is slidably mounted on the guide rail 71. The bottom of the slide 72 is fixedly connected to the center of the annular slide rail 74 by a connecting rod 73. A sliding sleeve 75 is slidably mounted on the annular slide rail 74, and a cross plate 76 is rotatably mounted on the side wall of the sliding sleeve 75. A linear slide groove 761 is provided on the upper end of the cross plate 76, and a support slide 762 is slidably mounted in the linear slide groove 761. A mounting plate 8 is provided above the support slide 762, and the bottom of the mounting plate 8 is rotatably matched with the support slide 762 through a connecting seat 81. A leveling cylinder 765 is rotatably mounted on one side of the support slide 762, and the output end of the leveling cylinder 765 is rotatably connected to the bottom of the mounting plate 8. A mounting plate 9 is arranged at intervals above the mounting plate 8, and a placement table 91 is fixedly provided on the upper end of the mounting plate 9. A number of clamping plates 92 for clamping the end head template are slidably mounted in the placement table 91.

[0034] Specifically, by setting up the transfer assembly 7, when the end head template is transferred, the slide 72 is first moved linearly along the guide rail 71 to transport the cross plate 76 to a position aligned with the operating table window 21, and the sliding clamping sleeve 75 drives the cross plate 76 to slide along the annular slide rail 74, so that the mounting plate 8 and the mounting plate 9 on the cross plate 76 gradually approach the operating table window 21, and the staff places the end head template between the two adjacent clamping plates 92, and the clamping plates 92 clamp the end head template, and then the slide 72 drives the cross plate 76 to move linearly along the guide rail 71, and cooperates with the sliding clamping sleeve 75 to drive the cross plate 76 to rotate along the annular slide rail 74, so that the cross plate 76 gradually approaches the side steel molds 4 on both sides, and uses the support slide 76 2 drives the mounting plate 8 to move along the linear slide 761, which can effectively adjust the horizontal position of the end template. The rotation process of the horizontal plate 76 drives the horizontal plate 76 to adjust the pitch angle, which can effectively adjust the height position of the end template. At the same time, the leveling cylinder 765 is used to adjust the inclination angle of the mounting plate 8, so that the mounting plate 8 can always remain horizontal during the deflection of the horizontal plate 76, ensuring that the end template remains stable and does not tilt during the transportation process. When the end template is transported to the designated workstation, the clamping plate 92 is released to unload the end template, thereby realizing the rapid transportation process of the end template from the construction platform 2 to the installation workstation, which is beneficial to improving the lining construction efficiency and greatly reducing the labor intensity of workers.

[0035] like Figure 4 and Figure 5 As shown, a roller 751 is rotatably installed in the sliding sleeve 75 , and the roller 751 rolls against the side wall of the annular slide rail 74 .

[0036] Specifically, when the sliding sleeve 75 rotates along the annular slide rail 74 , the roller 751 always rolls against the side wall of the annular slide rail 74 , thereby effectively ensuring that the sliding sleeve 75 slides smoothly and steadily on the annular slide rail 74 .

[0037] like Figure 6 As shown, limiting grooves 763 are provided on both side walls of the horizontal plate 76, and limiting sliders 753 are slidably installed in the limiting grooves 763. The side walls of the sliding sleeve 75 are rotatably matched with one end of the connecting rod 752, and the other end of the connecting rod 752 is rotatably matched with the bottom of the limiting slider 753. A locking bolt 754 is provided at the bottom of the limiting slider 753, and a locking groove 764 corresponding to the locking bolt 754 is provided along the length direction at the bottom of the horizontal plate 76.

[0038] Specifically, when the pitch angle of the cross plate 76 is adjusted, the connecting rod 752 will drive the limiting slider 753 to slide along the limiting slide groove 763 accordingly. When the cross plate 76 has adjusted the deflection angle, the locking bolt 754 is rotated to make it press against the locking groove 764. At this time, the position of the limiting slider 753 will be locked and fixed, so that the connecting rod 752 can be used to support and limit the cross plate 76, ensuring that the cross plate 76 can remain fixed after the deflection adjustment.

[0039] like Figure 7 As shown, a screw 82 is provided at the upper end of the mounting plate 8, and both ends of the screw 82 are rotatably mounted on a rotating seat. A servo motor 83 is fixedly provided on the rotating seat at one end, and a driving wheel 831 is sleeved on the output shaft of the servo motor 83. A transmission wheel 821 is sleeved on one end of the screw 82, and a transmission belt 822 is provided between the transmission wheel 821 and the driving wheel 831.

[0040] like Figure 7 and Figure 9 As shown, a threaded sleeve 84 is provided on the screw rod 82, a movable plate 85 is fixedly provided on one side of the screw sleeve 84, a sliding seat 852 is provided at the end of the bottom of the movable plate 85 away from the screw sleeve 84, and an auxiliary slide rail 86 is fixedly provided on the upper end of the mounting plate 8, and the sliding seat 852 slides in cooperation with the auxiliary slide rail 86.

[0041] Specifically, the servo motor 83 is started, driving the driving wheel 831 to rotate. The driving wheel 831 will drive the transmission wheel 821 to rotate through the transmission belt 822. The transmission wheel 821 will drive the screw 82 to rotate. By utilizing the threaded cooperation between the screw 82 and the screw sleeve 84, the screw 82 will drive the screw sleeve 84 to move in a straight line when rotating, so that the movable plate 85 will be displaced synchronously with the screw sleeve 84 along the auxiliary slide rail 86.

[0042] like Figure 7 and Figure 9 As shown, a mating groove 851 is provided through the movable plate 85, and the mating groove 851 is mirror-symmetrical about the mid-perpendicular line of the movable plate 85. The distance between the top ends of two adjacent mating grooves 851 remains consistent, and the distance between the bottom ends of two adjacent mating grooves 851 also remains consistent, and the distance between the top ends of the mating grooves 851 is greater than the distance between the bottom ends.

[0043] like Figure 9 As shown, supporting side plates 921 are extended to both sides of the bottom of the clamping plate 92 , and a pin rod 922 is fixedly provided at the bottom of the clamping plate 92 , and the pin rod 922 is adapted to be slidably installed in the corresponding matching groove 851 .

[0044] Specifically, by setting the clamping plate 92, the movable plate 85 utilizes the sliding cooperation between the pin rod 922 and the matching groove 851 during the linear displacement process, combined with the mirror arrangement of the matching groove 851 and the equidistant distribution design of the end portions, so that the clamping plates 92 can be equidistantly approached to each other for gathering, and equidistantly moved away from each other for dispersion, thereby being able to clamp and fix or loosen and unload multiple groups of end formwork at the same time, and because the clamping spacing between adjacent clamping plates 92 is always kept consistent, the thickness of the clamped end formwork should also be kept consistent. After multiple groups of end formwork are clamped and fixed, it is possible to intuitively judge whether their thickness meets the construction standard based on whether some of the formwork is loose, thereby realizing the thickness detection and screening process of the end formwork, which is beneficial to improving the quality of lining construction.

[0045] like Figure 8 and Figure 9 As shown, a clearance groove 901 is provided at the upper end of the mounting plate 9 for the pin rod 922 to pass through, a side slide groove 911 is provided inside the placement table 91, and the support side plate 921 is slidably installed in the side slide groove 911, and a clearance opening 912 is provided in the center of the placement table 91 for the clamping plate 92 to move back and forth.

[0046] Specifically, the give way groove 901 can provide sufficient space for the smooth movement of the pin rod 922, and the give way groove 901 also constrains and limits the pin rod 922, so that the pin rod 922 can only slide along the give way groove 901; the sliding cooperation between the supporting side plate 921 and the side slide groove 911 can effectively improve the stability of the clamping plate 92 during the moving and clamping process; the give way mouth 912 can provide sufficient space for the clamping process of the clamping plate 92.

[0047] like Figure 1 and Figure 2 As shown, a number of driving rods 11 are arranged at the bottom of the frame 1, and the output end of the driving rod 11 is fixedly connected to the positioning locking block 12. A top cylinder 13 is fixedly provided at the top of the frame 1, and the output end of the top cylinder 13 is fixedly connected to the top steel mold 3. Side cylinders 14 are rotatably installed on both sides of the frame 1, and the output end of the side cylinder 14 is rotatably connected to the side steel mold 4.

[0048] The working principle of the present invention is as follows: Figure 1 — Figure 9As shown, when lining the tunnel portal, the frame 1 is first moved to the construction area along the driving track 5 by the power assembly 6. After the top steel formwork 3 and the side steel formwork 4 are pushed into place, the end formwork is prepared for installation. When transferring the end formwork, the slide 72 is first moved linearly along the guide rail 71 to transport the cross plate 76 to a position aligned with the operating platform window 21. At the same time, the sliding sleeve 75 drives the cross plate 76 to slide along the annular slide rail 74, so that the installation plate 8 and the mounting plate 9 on the cross plate 76 gradually approach the operating platform window 21. The staff places the end formwork between two adjacent clamping plates 92, and the clamping plates 92 clamp the end formwork. The cam 762 of the support frame 761 of the lifting position is moved along the guide rail 74 so that the support rail 74 is moved along the guide rail 74, and the support rail 762 of the support frame 761 of the lifting position is moved along the guide rail 74, thereby effectively adjusting the horizontal orientation of the end template. When the end head template is clamped by the clamping plate 92, since the clamping spacing between adjacent clamping plates 92 is always kept consistent, the thickness of the clamped end head template should also be kept consistent. When multiple groups of end head templates are clamped and fixed, it is possible to intuitively judge whether their thickness meets the construction standard based on whether some of the templates are loose, thereby realizing the thickness detection and screening process of the end head template.

[0049] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
